Associations between proteins and volume-based mammographic breast density. Anti-FOXP3 (HPA045943) revealed significantly elevated signal intensities (p < 0.05) in women with high absolute volumetric breast density (High VD) compared to women with low absolute volumetric breast density (Low VD). The two samples groups (High VD/Low VD) represent the selection made for the original study design, where the two groups were carefully matched on age and body mass index. Normalised mean fluorescence intensity (MFI) values for women in Sample Set 1 (left) and Sample Set 2 (right) are shown. P values were generated using the Wilcoxon signed-rank test
